Early life

Wu studied statistics at the University of Melbourne and graduated in 1972. [1] She worked at Monash University as a research assistant from 1973 to 1975, where she taught herself to program. [2] She worked with Watterson on the Watterson estimator, a means to determine the genetic diversity of a population. [2]

Research and career

Wu joined CSIRO as a technical officer in 1977. [1] She earned a graduate diploma in computer studies from the Royal Melbourne Institute of Technology in 1985. Wu became a high school teacher at Ivanhoe Girls' Grammar School, teaching Chinese and mathematics. [1] She was appointed as a senior research fellow in the Australian Council of Educational Research Development (ACER) in 1992, where she was deputy director of Programme for International Student Assessment (PISA). Working with ACER and the University of Melbourne, Wu completed her master's, which was awarded the Freda Cohen Award for the Best Masters Thesis in Education. Wu remained at the University of Melbourne for her PhD, modelling student assessment data with underlying abilities modelled as latent variables. [1]

She was appointed associate professor at the University of Melbourne in 2008. She studied whether collaborative teams of teachers using evidence-based decisions influenced student achievement. [3] She was made a professor at Victoria University, Melbourne in 2012. Wu is sceptical about the importance of the National Assessment Program – Literacy and Numeracy (NAPLAN) and PISA results due to measurement errors acquired during collection of data. [4] She is also concerned about the inferences that can be drawn from assessment data, such as using student performance to evaluate teacher performance. [5] [6] [7] She believes that whilst teachers contribute to education, other factors are likely to be more important. [8] After the data was published on the website My School, Wu began to speak up about the misuse of standardised testing. [8] [9] Her efforts resulted into an enquiry into the effectiveness of NAPLAN. [10] Her findings were confirmed in 2018, when Les Perelman and Walt Haney reported that NAPLAN results of one million students should "be discarded". [11] [12]

In 1995, Wu began to concentrate on the development of Item Response Theory. [13] She developed two item response software programs that analyse PISA and TIMSS data; ACER ConQuest (1998) and the R-package TAM (2010). [14] [15] [16]

Wu's contributions to the Watterson estimator were uncovered by a team of undergraduate students led by Emilia Huerta-Sánchez (Brown University) and Rori Rohlfs (San Francisco State University). [1] [2] [17] The students searched every issue of Theoretical Population Biology published between 1970 and 1990. She was one of several "acknowledged programmers", who were disproportionately women, who contributed significantly to highly cited manuscripts. [17]

Education in Australia encompasses the sectors of early childhood education (preschool) and primary education, followed by secondary education, and finally tertiary education, which includes higher education and vocational education. Regulation and funding of education is primarily the responsibility of the States and territories; however, the Australian Government also plays a funding role.

Educational assessment or educational evaluation is the systematic process of documenting and using empirical data on the knowledge, skill, attitudes, aptitude and beliefs to refine programs and improve student learning. Assessment data can be obtained from directly examining student work to assess the achievement of learning outcomes or can be based on data from which one can make inferences about learning. Assessment is often used interchangeably with test, but not limited to tests. Assessment can focus on the individual learner, the learning community, a course, an academic program, the institution, or the educational system as a whole. The word "assessment" came into use in an educational context after the Second World War.

It was first performed in 2000 and then repeated every three years. Its aim is to provide comparable data with a view to enabling countries to improve their education policies and outcomes. It measures problem solving and cognition.

In each of the participating educational systems, a minimum of 4,000 to 5,000 students is evaluated. Contextual data about the conditions in which participating students learn mathematics and science are collected from the students and their teachers, their principals, and their parents via questionnaires.

In population genetics, the Watterson estimator is a method for describing the genetic diversity in a population. It was developed by Margaret Wu and G. A. Watterson in the 1970s. It is estimated by counting the number of polymorphic sites. It is a measure of the "population mutation rate" from the observed nucleotide diversity of a population. , where is the effective population size and is the per-generation mutation rate of the population of interest. The assumptions made are that there is a sample of haploid individuals from the population of interest, that there are infinitely many sites capable of varying, and that . Because the number of segregating sites counted will increase with the number of sequences looked at, the correction factor is used.

The Programme for International Student Assessment has had several runs before the most recent one in 2012. The first PISA assessment was carried out in 2000. The results of each period of assessment take about one year and a half to be analysed. First results were published in November 2001. The release of raw data and the publication of technical report and data handbook only took place in spring 2002. The triennial repeats follow a similar schedule; the process of seeing through a single PISA cycle, start-to-finish, always takes over four years. 470,000 15-year-old students representing 65 nations and territories participated in PISA 2009. An additional 50,000 students representing nine nations were tested in 2010.
